Thank you to Penon Audio for sending Head pie the H40.

Welcome to the ninth installment of the Head pie memes.

Series number eight is dubbed - ‘Lazarus’

Pie so serious?

Once again the memes regularly appear daily on Head pies Facebook group and instagram account for better or worse.

Its a mix of various themes and `imaginatings`.

Riffing constantly on the #headpiesucks storyline, satire and parody of the audio world at large.

*Many of the memes are best understood in context of the meme collections as a whole. all oops 1000 or so of them.

Head pie hard at work creating daily memes whilst the reviewing section suffers - i am turning down more review units than i accept. Especially garbage gear that it would be cruel to review and have others buy.

The advertising is still nil, as per 98% of other  reviewers out there - as usual with 97% of reviewers still no cash paid for the  crappy word salad reviews.

‘Its a hobby..’ - that takes a lot of time and energy.

I should STILL move to wordpress but meh, i am too lazy....

Enjoy. Are we having fun yet!??
